What the heck is… Machine Learning

Alex Wood: What is machine learning?Suranga Chandratillake: In the past, computer programmers needed to tell computers exactly what to do. The computers would then follow these instructed steps over and over. This limits computers to being dumb followers of instructions. Machine Learning aims to help computers learn about the world for themselves, by creating a more generic algorithm. These algorithms can be shown a lot of data, and they then figure out how to react to, or process the data for themselves. AW: How does it work? SC: There are a number of different approaches to creating these self-learning algorithms. Among the best known are artificial Neural Networks. These networks are modelled on the way biological neurons work. They take inputs (or signals) at one end, and allow the patterns that…
